ohh...it sounds like your tv cable came off or went out of adjustment suddenly. without that, you will lose your tranny in less than 5 miles, ive heard.
you can try rebuilding it yourself if you have the time. if you havent done it before, i wouldnt recommend it. mine was burned up too, and someone just gave it to me.

it took a tci pro super rebuild kit ($220, includes all frictions, steels, and shift kit), a drum (dont remember which one, $65), and that was pretty much it. i paid the tranny guy i used to work with, $200 to [re]build it. i picked up a b&m 2000 lockup converter ($150) and a tci hardened lockup input shaft ($75) from ebay, and bam! it should be good to go. your mileage may vary, of course.

have a good night man, it was nice talking to you too. you can find me on aim, msn, or yahoo too of course, if you need something answered fast, lol. just check the buttons under my avatar.
